Resumo(s)
Preterm birth, defined as birth before 37 weeks of gestation, affects approximately one in ten live-born infants globally. The risks and potential complications are more pronounced in infants born before 32 weeks, particularly those born before 28 weeks, necessitating specialized monitoring of developmental outcomes. Traditional developmental assessments often rely on performance-based observations, which can be subjective and may not detect subtle or delayed difficulties that emerge later, such as in school-age children. This study presents the development and pilot application of a comprehensive protocol designed for the objective and integrated collection of clinical, developmental, and electrophysiological data to evaluate the impact of preterm birth. The protocol involves monitoring two groups of healthy infants-preterm and full-term four time points during the first year (4, 6, 9, and 12 months). Assessments include clinical evaluations, the Bayley Scales of Infant and Toddler Development, and electrophysiological recordings such as visual evoked potentials (VEP), electrodermal activity (EDA), and an ophthalmological screening assessment at 4 months. Two case examples (one full-term, one preterm) are provided to illustrate data collection and application. While the article does not include outcome analysis, it emphasizes protocol structure and applicability, offering a foundation for future longitudinal study.
Descrição
This work was supported by Fundação para a Ciência e Tecnologia (FCT, Portugal) through national funds [UI/BD/151321/2021] and [LA/P/0117/2020] The research group, particularly AIF, gratefully acknowledges the clinical staff of the Neonatology Service at Dr. Alfredo da Costa Maternity, as well as the Ophthalmology and Neurophysiology teams from Dona Estefânia Hospital, for their warm reception of the project idea and their collaboration in the development of the protocol. We also extend our appreciation to the master’s students in Biomedical Engineering for their valuable contributions during the development of the experimental protocol and data processing algorithms. Last but certainly not least, we acknowledge the parents and infants who participated in the protocol development and pilot application.
